Fix LIBC_PROG_BINUTILS for -fuse-ld=lld
GCC does not print the correct linker when -fuse-ld=lld is used with
the -print-prog-name=ld:
$ gcc -v 2>&1 | tail -n 1
gcc version 11.2.0 (Ubuntu 11.2.0-7ubuntu2)
$ gcc
ld
This is different than for gold:
$ gcc -fuse-ld=gold -print-prog-name=ld
ld.gold
Using ld.lld as the static linker name prints the expected result.
This is only required when -fuse-ld=lld is used, if lld is used as
the 'ld' programs (through a symlink) LIBC_PROG_BINUTILS works
as expected.
Checked on x86_64-linux-gnu.
